The exchange of information between distant sources is the basis of all communications, but quantum mechanics may open up this distant exchange as never before. Quantum key distribution, for instance, would allow for absolutely secure encryption of information exchange by encoding information keys on single photons.

Unexpected findings suggest need for alternate therapeutic approaches, different animal models for future research. One of the characteristics of the brain of people with Alzheimer disease (AD) is the presence of tangles, insoluble twisted fibers that build up inside the nerve cells of the brain resulting in malfunctions in communication between nerves and later in their death. A new study finds that the Pin1 enzyme, previously shown to be of benefit in "detangling" tau in Alzheimer's disease, actually has the contradictory effect in cases in which the tau has certain mutations.

Score one for the nurture side of the nature vs. nurture debate, as geneticists have shown that environmental factors such as lifestyle and geography play a large role in whether certain genes are turned on or off. By studying gene expression of white blood cells in 46 Moroccan Amazighs, or Berbers -- including desert nomads, mountain agrarians and coastal urban dwellers -- the researchers in Morocco and the United States showed that up to one-third of genes are differentially expressed due to where and how the Moroccan Amazighs live.

Sixty-five percent of American women between the ages of 25 and 45 report having disordered eating behaviors, according to the results of an online survey. An additional 10 percent of women report symptoms consistent with eating disorders such as anorexia, bulimia nervosa and binge eating disorder, meaning that a total of 75 percent of American women surveyed endorse some unhealthy thoughts, feelings or behaviors related to food or their bodies.

In a study that points to a new strategy for preventing or possibly reversing fibrosis -- the scarring that can lead to organ and tissue damage -- researchers have determined that a molecule called Epac (Exchange protein activated by cAMP1), plays a key role in integrating the body's pro- and anti-fibrotic response.

Overall life expectancy in the US increased more than seven years for men and more than six years for women between 1960 and 2000. Now, a new, long-term study of mortality trends in U.S. counties over the same four decades reports a troubling finding: These gains are not reaching many parts of the country; rather, the life expectancy of a significant segment of the population is declining or at best stagnating.
